Can any one of you please tell me what actually happens when user checks that prompt message not to display any more dialog box. Why I am asking this question is when user selects that box, from next time system not performing any action that was done before when it was displaying that pop-up message.

Your reply helps me a lot to understand this issue.

Thanks,
Anilkumar

It is a feature of Firefox (maybe other browsers) to prevent a webpage 
from annoying users by creating a stream of alerts.

Try this:

<script type="text/javascript">
while (true){
   alert("try to shut this page down!");
}
</script>

Such a script hijacks the browser, since it is close to impossible to 
hit the close button before the new alert appears.

It is a feature of all Mozilla-based software, including Firefox:
